Reversal of Input Tax Credit on switching to composition scheme; capital goods credit prorated by remaining useful life.
Switching to the composition scheme requires reversal of Input Tax Credit on inputs, inputs in semi finished or finished goods held in stock, and capital goods held in stock as on the day before the option is exercised, by payment from the electronic credit or cash ledger after prescribed reductions. For capital goods, reversal is prorated by remaining useful life using an assumed five year useful life, with the credit attributable to remaining months computed as original credit multiplied by remaining months divided by sixty.

Input tax credit eligibility on switching from composition to normal scheme - capital goods credit reduced over time, subject to time bar.
A taxpayer switching from the composition scheme to the normal scheme may claim Input Tax Credit for inputs, inputs in goods held in stock, and capital goods held immediately before liability to pay tax, but credit for capital goods must be reduced by the prescribed periodic reduction measured from the invoice or receipt date, and no credit may be claimed for supplies after one year from the tax invoice date.
